Turbo Question - Cam Selection - Help Please

[PaulFiveOh]

First Off! I am in no way doubting what "my" expert is saying, I am just seeing what everyones opinion is on this subject.

Setup-
Stock block - blocks been decked, align honed, all the goodies etc.
Lightened & Balanced STOCK crank
High Comp :( 10:1 Diamond Pistons with file fit speedpro rings
Eagle Rods
ARP fasteners
DSS Main Girdle
Thick high dollar fel pro head gasket
All bearings and internal components have less than 500 miles

T70 Journal Bearing Turbo w/ a good intercooler looking at like 10lbs (??) I guess...
Water/Meth Injection to combat that freaking 10:1 comp.
Healthy 60lb injectors with a 255lph in tank pump (is a single 255 big enough?)
GT40 Heads with mild work on a GT40 upper/lower fed by a 70mm TB
Stock high mileage T5 :tard: with a strong SPEC clutch
All handled by what will be a MD tuned SCT piggyback on a A9L.

Question:
The thing I am desperately trying to avoid is splitting my block in half down the cam valley. Further more, I dont want the block to split or crack at all, any where. You know, 1 block, 1 peice is the goal :rolleyes:.

The engine I have listed above has a stock H.O. cam shaft.
I want to put in a bigger anderson cam aprox .519.
My expert tells me to leave the stock cam in because I will be fighting power.
I completely understand his point, i mean, duh, bigger camshaft=more power= broken block.
But, my question is:
Should I leave the stock cam in?
Should I put my bigger .519 cam in and take the power out of some where else?

Please shed your experience and what you have all ready learned from trial and error with me.

Thank you!

Leave the stock cam in place, it will make way more power than your block can take. The T70 is pretty good size unit for a 302, so with the right block, it can make some big power. 10.0:1 is high for a street driven turbo motor, why not open up the chambers on your heads to drop it down some? Don't make the mistake of putting thicker head gaskets on it either. Also, keep in mind that the lift on the cam (in your application) isn't nearly as important as the rest of the #'s. Also, blower cams aren't the same as turbo cams.

Man I can only wonder who "your" turbo expert is, LMAO!!!!!

Leave the stocker in there. Dedpedal had a bunch of issues with an aftermarket cam(don't remember the whole deal), but he put the stock bumpstick back in and made very good power.

Do you think that high mileage t5 will hold up?

Man I dunno....there's might be a small chance that it could be!!

No. Not at all.

But its all good.

Thanks for most of your input.

I will leave the stocker in there.

Have you considered a custom cam? Seems like you have some very nice parts there, why not spend the extra $350 and get a nice custom cam?

[347sc]

Be a waste of money better spent elsewhere.

I have a stock cam in my car and it makes around 700 rwhp. I would stick with the stocker.
